Frequently Asked Questions about Roller Encoders
Question number FAQ-0131
To set the signal output of the RP-700 series roller encoders to open collector (Applicable models: RP-721, RP-732, RP-704ZA)
Please use the dedicated amplifier model PA-330ZC.
The PA-330ZC amplifier is a modified version of the PA-330Z amplifier, where the 330Ω resistor in the output circuit has been removed (optional).
The diagram below is an overview of the PA-330ZC configuration..
